Coding vs. the Brain: Can’t We All Just Get Along?
1. Alfa
Time: 2015/11/19 09:10 - 10:10
In an extremely short time interactive information appliances such as mobile devices, computers, and
interactive kiosks such as ATMs have exploded into common use all over the globe. An understanding
of how these appliances work must now join arithmetic and the calendar in the migration toward uni-
versally accessible simplicity. This migration will require a radical simplification of the conceptual model
for the internal workings of interactive appliances that is more intuitive than algorithms for the mass
of people.
The talk presents a hybrid unidirectional-flow/message model of the internal operation of interac-
tive information appliances that is intuitive, generally applicable, and largely algorithm-free. It also
presents design principles that formalize what-you-see-is-what-you-get construction-tool behavior.
Finally, the talk demonstrates a proof-of-concept application builder that conforms to these de-
sign principles and that builds small applications that work according to the new conceptual model.

The last programming language
1. Alfa
Time: 2015/11/18 09:15 - 10:15
For the last 50 years we’ve been exploring language after language. Now many of the “new” languages
are actually quite old. The latest fad is “functional programming” which got it’s roots back in the 50s.
Have we come full circle? Have we explored all the different kinds of languages? Is it time for us to
finally decide on a single language for all software development? In this talk Uncle Bob walks through
some of the history of programming languages, and then prognosticates on the future of languages.

Retinas and One Small Step
1. Alfa
Time: 2015/11/20 10:00 - 11:00
Looking back through history, we often view NASA’s early mission in terms of “getting to the Moon”,
discussing how this or that program served the purpose of answering Kennedy’s challenge. This is
wrong-headed. In this talk I will discuss aeronautics research beginning with the Writght Brothers and
ending with the first Shuttle launch in 1981. We’ll see how NASA is an organization whose primary mis-
sion is basic research and development in aeronautics for the benefit of the public at large and space ex-
ploration. We’ll see how the Lunar Program was a focusing of research to a practical, political aim which
built off decades of basic research and necessarily side-lined other programs. It’s my aim to convince
you that Moonshot projects cannot be considered independently of their organizations and its history.

Categories for the Working Programmer
2. Beta
Time: 10:35 - 11:30
The Haskell community is famous - perhaps infamous - for its enthusiasm for
category theory. Why is this? Is it important to understand categories before
you can understand Haskell programs? Is it an attempt to keep the community
as pure as the language? Is it just that Haskell is a refuge for underemployed
mathematicians? None of the above! In this talk, I hope to explain a little bit
about how categories can help the working functional programmer. I’ll focus on
categories as an organising principle, helping us to manage generic libraries. No
monads were harmed during the making of this talk.

Refactoring Legacy Code
5. Theta
Time: 10:35 - 11:30
Every programmer has to face legacy code day after day. It might be ugly, it
might look scary, it can make a grown man cry. Some will throw it away and try
rewriting everything from scratch. Most of them will fail. Refactoring legacy
code is a much better idea. It is not so scary when you take it in very small
bites, introduce small changes, add unit tests. When code is refactored and unit
tests are added, changes to functinality can be introduced. We will take an
open source c# project and will refactor it showing step-by-step examples of
the techniques. This session is full of tips and tricks you can start applying
immediately. Although the code is in C#, the same principles can be applied
in any language

Microservice - no fluff the REAL stuff
5. Theta
Time: 11:50 - 12:45
Some developers tend to believe that big data and huge traffics are pre-requi-
sites to harness and reap the benefits offered by microservices. However, there
are many problems like polyglot persistence, faster continuous build cycle,
shorter release plan, etc. that can be solved by applying microservice archi-
tecture even in smaller organizations. You don’t have to be a software giant to
leverage stability, effectiveness and flexibility provided by microservices. Micro-
service architecture has a lot to offer even for smaller organizations.In this talk,
we will walk through the key concepts like service discovery & registry,
circuit breaker, API gateway and edge service. Build a bunch of microservices
demonstrating practical implementation of these patterns using open source
components like Eureka, Zuul, Hystrix and powered by spring cloud.Lastly, we
will deploy our microservices on a container based solution, i.e.

Traditional approaches in anti-money laundering involve simple matching algo-

Time: 13:45 - 14:40
How to keep a real-time, low-latency and high-stakes system up and running

of them. And then some cool stack to do stuff with it. Forter is a company with
a Decision-as-a-Service product that deals with many e-commerce transac-

or not?”. And if we were wrong, we pay. In this talk I will show how we are using
various technologies to power our service and keep it high-available and well
under control. Among the technologies I will discuss are Apache Storm, Node.
js, Riemann (state machines in Clojure, yay!), collectd, D3.js and of course the
ELK stack (and beats!). Some integrations which will be mentioned include
PagerDuty, Slack, Jenkings and GitHub.

Evil by Design
5. Theta
Time: 13:45 - 14:40
In this talk, I’ll share what my experience has been working in the gambling
business, how moving to events helped us gain a better understanding of the
domain and which techniques and models casinos have perfected over the years
to keep people playing. --- Last year I ventured into the domain of (online)
gambling. Given that the industry has been around since forever, I expected
most problems to be of the technical kind. As it turned out, the struggle with
technology was only part of a bigger problem; to move forward we needed to
fully grasp the industry and its consumers. Domain events started out as a
way to dismantle a legacy system, but quickly proved to be an effective tool
to gain a deeper understanding of our domain. Visualizing event streams, we
discovered patterns that helped us identify what drives different types of users.
Having a better understanding of what customers are looking for, we dove into
existing literature to learn which techniques and models casinos use to cater for
each type of user. We learned how to program chance while staying true to the
Random Number God. Even when variance is brutal, casinos have enough data
and tools to steer clear from the pain barrier. All of this entails interesting
problems and software, but isn’t my code damaging society? Or is gambling just
another human trait?

The Liberal Arts Programmer
1. Alfa
Time: 15:00 - 15:55
At a certain point software was everything in my life. Learning new languages,
architectures, design patterns and acquiring skill in practice - my raisons d’etre.
After a while things clicked, and I started leading teams of more junior program-
mers. “The People Problem” presented new and foreign challenges. There’s
nothing quite like working with others on real products to transform egocentric
practice into empathic pragmatism. My search for a new bag of tricks led me
back to my earlier studies in the humanities. Suddenly my liberal arts education,
formerly regarded as tangential even if interesting, felt applicable to more than
cocktail party conversation. In this talk we’ll look at disciplines outside the
purview of software development with an eye for how borrowed ideas can yield
not only inspiration and analogy, but real innovations and breakthroughs. I’ll
share examples from fine art, psychology, history and literature influence my
approach and the work of others.

Creating a scalable, repeatable infrastructure with Terraform
4. Zeta
Time: 15:00 - 15:55
The age old task of racking and stacking in a physical data centre is becoming
more and more rare as more companies embrace the public cloud. Having the
ability to choose between providers such as AWS, Azure, Digital Ocean and
Google Cloud Platform makes creating infrastructure easy. It is better to spend
time developing better services for our customers than managing infrastructure
During this talk, Paul will demonstrate how building a scalable infrastructure on
AWS becomes easy with Terraform. The talk will demonstrate how using config-
uration management, pre-baked AMIs and auto-scaling groups it gives the abil-
ity for developers to be able to launch their own infrastructure when needed. The
demos will include the ability to launch instances, databases and manage user ac-

Service Architectures at Scale: Lessons from Google and eBay
1. Alfa
Time: 11:45 - 12:40
Over time, almost all large, well-known web sites have evolved their architec-
tures from an early monolithic application to a loosely-coupled ecosystem of
polyglot microservices. While first-order goals are almost always driven by the
needs of scalability and velocity, this evolution also produces second-order ef-
fects on the organization as well. This session will discuss modern service archi-
tectures at scale, using specific examples from both Google and eBay. It will
cover some interesting - and perhaps nonintuitive -- lessons learned in building
and operating these sites. It continues with some more advanced implications of
a microservices architecture, including SLAs, cost-allocation, and vendor-cus-
tomer relationships within the organization. It concludes by exploring a set of
common service anti-patterns.

The T in TDD: Test, Types, Tales
4. Zeta
Time: 11:45 - 12:40
Test-Driven Development is about writing a test first, then the code that satis-

evolved dramatically. Nowadays, I barely test first, but spend my days in the
scripting environment. In this talk, I will examine how I write code in F# today,
in a style I consider very much inspired by TDD; I will also discuss how exploring
two paradigms (C# and F#) forced me to re-examine my beliefs, and evolve a
slightly different (and perhaps less language specific) understanding of some of
the same core principles.

Functional Programming for the Object Oriented
5. Theta
Time: 11:45 - 12:40
Most modern programming languages have taken inspiration from the func-
tional programming paradigm and have implemented features for making
functional modelling easier. To be able to fully leverage the power of languages
such as C#, it is therefore necessary to have an understanding of functional
programming as well as other paradigms such as object orientation. This presen-
tation gives an introduction to Haskell and compares it to the features provided
in C# that have been influenced by concepts from the functional world. In par-
ticular, it aims to illustrate how a functional approach to solving problems differs
from an object oriented approach.

Functional Programming You Already Know

From JVM to .NET languages, from minor coding idioms to system-level archi-

Functional programming is certainly not a new idea and, although not appar-
ently as mainstream as object-oriented and procedural programming, many of
its concepts are also more familiar than many programmers believe. This talk
examines functional and declarative programming styles from the point of view
of coding patterns, little languages and programming techniques already famil-
iar to many programmers.

Time: 14:55 - 15:50
Brighter http://iancooper.github.io/Paramore/Brighter.html is an OSS library
for .NET that allows you to build a robust, fault-tolerant Command architec-
ture for .NET. It supports pipelined execution of commands both in-process
and via a Task Queue, and was highlighted in the May 2015 ThoughtWorks
Technology Radar. In this presentation we look at what Brighter is, how it does
it, and show you how to build robust distributed system with it.

Artificial Intelligence that plays
Atari video games: How did DeepMind do it?
2. Beta
Time: 14:55 - 15:50
We replicated the work of DeepMind as an open source project and created
an artificial intelligence that can learn to play different video games in a su-
per-human level without any human intervention. I will talk about deep learning,
reinforcement learning and their combination called deep Q-Network.

Onboarding at Scale: An Engineering Problem
4. Zeta
Time: 14:55 - 15:50
Of the myriad challenges in scaling up an engineering organization, onboard-
ing new employees is probably the least well-understood. There are relatively
common solutions for large-scale recruitment, finance and administration, but
onboarding remains a question that many organizations struggle with. At Wix
we’ve been struggling with massive scaling challenges: over the last two years
our company headcount has doubled itself, and we had to learn to cope with
the influx while maintaining velocity. In this talk we’ll share with you the story
of how we set up Wix Academy, an engineer-driven training organization, the
solutions we’ve developed (and still are!), and what we’ve learned in our first
year of operation.

BARBARA FUSINSKA
Analysing GitHub commits with R
5. Theta
Time: 14:55 - 15:50
R has made the world of data analysis more approachable and has become an
important tool for computational statistics and data visualization. With Micro-
soft acquiring Revolution Analytics, the creators behind R and related tooling,
it’s also now a part of the Azure family. In this tutorial, Barbara will demon-
strate how you can use R to turn application data into business insights and
actionable statistics. Using Github Archive, an event based commits datasets
as an example, Barbara will ask the vital questions such as which languages have
had interesting trends and who the influencers within each category are. The
records also reveals interesting conclusions about future trends and why partic-
ular repositories are more popular than others. By developing intuition about
the data sets and investigating them with more formal statistical methods, data
can shape your business to be more profitable. At the end, attendees will under-
stand the power of the R language and how they can apply the same approaches
for analysing Github’s commits for their own application allowing them to turn
unstructured data into information that could be potentially monetised.

Let’s Get Lazy
1. Alfa
Time: 11:20 -12:15
How can big data or highly responsive applications scale to the increasing de-
mands for speed and short response time? Adding more servers to the cluster is
not the answer. The smartness comes from being lazy as laziness can translate to
efficiency and scalability. In this presentation we will learn about what lazy eval-
uation is, explore some data structures and APIs that promote lazy execution,
and tie it back into scalability and efficiency.

CIDER: Building a Clojure Interactive
Development Environment that Rock in Emacs
2. Beta
Time: 11:20 -12:15
This talk is dedicated to CIDER - an interactive development environment for
Clojure. CIDER is the most popular programming environment in the world of
Clojure these days and it’s quite unique, for it’s not a plugin for IntelliJ, Visual
Studio or Netbeans; quite the contrary - it’s built on top of the Emacs editor
and it still provides a ton of cool features that most IDE users have come to love
and expect from a modern programming environment. We’ll discuss whether
(why) it’s a good idea to build dev tools on top of Emacs, the history of the
project, its current state and the bold plans for its future. Be advised - by the
end of the talk you’ll probably become an Emacs user for life, so attend it at
your own risk! :-)

Life without Objects
5. Theta
Time: 11:20 -12:15
Transitioning from OOP to functional style can be quite challenging, not least
because OO programmers are used to thinking in nouns. Programming lan-
guages that use functions as primary means of abstraction force one to: - de-
sign things in terms of verbs, - find new ways of doing composition, - rediscover
polymorphism in a different light. Fear not! What you have learned about good
OO design can be applied to FP, in obvious and weird ways. Code examples will
be presented in Clojure.

The Slow Steady Industry Move Toward Tacit Programming
1. Alfa
Time: 13:15 -14:10
We’re all aware that the industry is moving from Object-Orientation toward
Functional Programming, but the move may be even deeper than that. As we
adopt a strongly compositional style using tools like LINQ, Rx, Java Streams,
and Ruby’s Enumerable, we find that we approach a type of programming that
is closer to what is common in the APL family of languages. This talk will explore
the trend and its possible ramifications.

Monoliths to Microservices. A Journey
2. Beta
Time: 13:15 -14:10
Your monolithic system is a pain to work with and maintain. Moving to a dis-
tributed system will solve all your problems and you will be in developer heaven.
Right? You will be working with cool technologies and amazing concepts. Plus,
it’s Microservices! So what could possibly go wrong? In this talk Sam Elamin
will relate his real life experience migrating a single ASP.NET application with
a monolithic database to a distributed system dealing with £100,000
transactions every hour. Sam will cover the challenges faced, the lessons
learned, and offer some final takeaways. This “from the trenches” story will
show you the pitfalls to avoid when doing Microservices.

Crunching through big data with MBrace, Azure and F#
4. Zeta
Time: 13:15 -14:10
For data exploration and rapid prototyping, the productivity of an interactive
scripting environment is hard to beat: simply grab data, run code, and iterate
based on immediate feedback. However, that story starts to break down when
the data you have to process is big, or the computations expensive. Your local
machine becomes the bottleneck, and you are left with a slow and unresponsive
environment. In this talk, we will introduce MBrace.net, an open-source and
free engine for scalable cloud programming. Using the MBrace programming
model, you can keep working in your beloved familiar scripting environment,
and easily execute C# or F# code on a cluster of machines on Azure. We will
focus primarily on live demos, from provisioning an Azure cluster with Brisk, to
analyzing large datasets in a distributed fashion; in particular, we will discuss how
this setup is relevant to data science and machine learning.

Mutate your code and reveal you true test coverage
5. Theta
Time: 13:15 -14:10
Session is about mutation testing, why and when you should mutate your code.
What benefits comes by mutating your code. Simply test your own tests. It’s
very helpful tool with TDD where you are exposed to a lot of wrong assumptions
and simple syntactic errors that can propagate other errors.

Programming with GUTs
1. Alfa
Time: 14:30 -15:25
These days testing is considered a sexy topic for programmers. Who’d have
thought it? But what makes for good unit tests (GUTs)? There’s more to effec-
tive unit testing than just knowing the assertion syntax of a framework. Test-
ing represents a form of communication and, as such, it offers multiple levels
and forms of feedback, not just basic defect detection. Effective unit testing
requires an understanding of what forms of feedback and communication are
offered by tests, and what styles encourage or discourage such qualities. What
style of test partitioning is most common, and yet scales poorly and is ineffec-
tive at properly expressing the behaviour of a class or component? What styles,
tricks and tips can be used to make tests more specification-like and can scale
as the codebase grows?

YAN CUI
My adventure with Elm
5. Theta
Time: 14:30 -15:25
Reactive Extensions (Rx) has brought reactive programming to the mainstream
in recent years with successful adoption in languages such as C#, Java and
JavaScript. But have you ever wondered what Rx will look like as a language?
Elm is a new programming language based on the idea of Functional Reactive
Programming (FRP). Elm lets you create highly interactive web applications
without all the messy callbacks tangling around shared states. In this talk Yan
Cui will give a gentle introduction to Elm and share his experience learning Elm
and recreating Missile Command in Elm with less than 250 LOC. You will leave
this session with a handle on the Functional Reactive Programming paradigm
and a basic understanding of the Elm language.

Ten Rules for API Design
1. Alfa
Time: 15:45 -16:40
Every software developer uses APIs and most of us make them. The design of a
“good” API is a black art. You know one when you see one. And yet how many of
us could explain why some APIs are complex and hard to learn, while others are
clean, simple, and a joy to use. It’s a question I’ll answer in this talk, and provide
ten rules for good API design.

Are smart systems making us stupid?
2. Beta
Time: 15:45 -16:40
The Turing Test will be passed by 2020. Not by an advanced artificial intelli-
gence, but by a human being who is stupider than their own phone Did you
read about the man who drove his car into a lake because Google Maps told him
to? Or the woman who put her phone into “airplane mode” and threw it out of a
window? Does Google ever freak you out by showing you stuff it’s not supposed
to know about? Software and smart devices are changing the world beyond
recognition, and all too often, the human beings who create it are struggling
to keep up. We create devices that can make crystal-clear hi-def video calls to
anywhere in the world, and then laugh at someone who microwaves their iPhone
because they read online that it would charge the battery. You spend $800 on
a tablet computer that doesn’t even include an instruction manual - and then
your three-year-old kid finds a shortcut for playing Peppa Pig videos that you
didn’t know existed. At the other end of the scale, we’re building huge distribut-
ed systems too complicated for any human to understand.

Continuous Delivery The Missing Parts
5. Theta
Time: 15:45 -16:40
A lot of developers have started to believe that hooking Visual Studio up to
Azure and pushing code direct from their machines is CD. As much as I hate
to say it, it isn’t. Continuous delivery has so many more moving parts required
to work together. As we discuss concepts such as config management, orches-
tration, security, monitoring and logging, this talk will help developers realise
that continuous delivery is something we need to continually measure, learn and
adapt to make us a higher achieving organisation.

JONATHAN GRAHAM
Reactive Systems: From Drug Development
to Functional Programming
4. Zeta
Time: 15:45 -16:40
Systems built as Reactive Systems are more flexible, loosely-coupled and
scalable. This makes them easier to develop and amenable to change. They are
significantly more tolerant of failure and when failure does occur they meet it
with elegance rather than disaster. Focus is given to designing systems that are
responsive to issues and constraints, through knowledge of the impact of ex-
ceeding standard operating ranges and the use of real-time analytics; resilient
to failures that could occur at any point within the system; elastic to changing
demands that occur during the lifecycle of manufacture through a flexible and
well understood approach to scalability; and message driven, whereby the re-
sources used and specifications required for a specific segment of the system
are derived by the demands external to that segment. In this presentation we
will use learnings from the Pharmaceutical Industry to explore the extent of the
Reactive Manifesto for software development, and we will look specifically at
how this relates to functional programming.
